Description

Technical Field

[0001] The invention belongs to the technical field of building curtain wall and hanging board wall connectors, and in particular relates to an embedded plate connecting component of a unit curtain wall and a unit hanging board wall. Background Art

[0002] The building unit prefabricated curtain wall and unit hanging panel wall are innovative solutions to the construction labor problem. However, the defects of the buried panel connection components are a global problem. After the building unit prefabricated curtain wall and hanging panel wall are assembled into large panels in the factory, in order to match the building structure and the indoor floor decoration finishing, they are coordinated with the interlayer horizontal beams of the unit curtain wall panels or the upper part of the hanging panel wall, so that the interlayer height of the unit horizontal beams or the upper part of the hanging panel wall is limited. Its on-site hoisting is also restricted by the installation without scaffolding, and the spatial conditions of the completed large panel connection are also limited. Electric tools or wrenches can only be operated on the limited surface of the floor.

[0003] Therefore, the common floor surface embedded parts in the world are beam sinking type and prefabricated floor heightening type. Among them, the concrete beam sinking type: in order to solve the normal indoor decoration, the beam width needs to be increased to 2-3 times the normal beam width, that is, about 500-700mm. In order to ensure that the embedded parts meet the relevant specifications of the anchor bar to the edge spacing, it is necessary to sink 50-100mm at about 300-350mm from the concrete edge. The sinking of the beam not only increases the cost of engineering construction, but also makes the construction very difficult. It often faces problems such as low slump of commercial concrete leading to uncontrollable flatness. Not only does the structural engineering construction unit resist, but its flatness will also increase the self-explosion rate of unevenly loaded glass. Prefabricated floor raising type: the ground is raised with 50cm×50cm small bracket-type floors to meet the needs of indoor floor decoration. However, this type of floor has problems such as furniture flatness and looseness during use, as well as poor decorative effect. Especially when encountering thin floors with prefabricated steel structures, only prefabricated floor raising type can be used, which is not popular.

[0004] In the existing method of sinking pre-embedded grooves in concrete beams to install platform codes and their hangers, the platform codes are bent upward to form hanging hooks. Due to the uneven concrete surface, the load-bearing of each unit block is uneven, forming a parallelogram stress. The load-bearing problem of the hooks on the platform codes under external tension and bending moment causes uneven load on the plane of the glass blocks to generate stress, resulting in a large number of glasses exploding every year, posing serious safety hazards to the project.

[0005] The purpose of the present invention is to provide a unitized buried plate connection assembly to solve the technical problem that the uneven force on the platform code leads to the spontaneous explosion of the curtain wall and the hanging plate. Summary of the invention

DETAILED DESCRIPTION

[0042] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] like Figure 1-2 As shown, the unit-type buried plate connection assembly includes a platform code 1, on which a connecting portion 2 and a hanging portion 3 are provided. The hanging portion 3 includes a hanging rod 31, and both ends of the hanging rod 31 are fixed and provided with a hanging clearance space cavity a.

[0044] In the face of uneven parallelogram stress caused by uneven concrete surface, the cantilevered suspension rod 2 has only two fixed supports at both ends, and the force on the suspension rod 2 is evenly dispersed. Under the action of the uneven reaction force of the uneven concrete surface, the force is concentrated on the two ends of the suspension rod 2, and the load is dispersed through the suspension rod 2, reducing the risk of bursting of the glass curtain wall and cracking of the external wall panels due to uneven loading. The two ends of the suspension rod 31 are fixed and a suspension clearance space cavity is provided in the circumference, which gives great flexibility to the suspension operation. It can adapt to the changes in the suspension angle caused by the deviation of the building structure and design requirements during the installation of different curtain wall units and external wall units, and improves the versatility. On the other hand, it ensures that during the subsequent installation and adjustment process, the curtain wall unit or the external wall unit can always maintain a relatively stable position, reducing the accumulation of installation errors caused by the initial unstable mounting, and ensuring the installation accuracy.

[0045] On the other hand, the setting of the suspension space cavity makes the suspension hook 43 on the suspension member 4 in the insertion direction. Figure 1 In the middle Z direction, it is not affected by the hanging depth. For the design of curtain walls and external walls, the flatness of the concrete floor needs to be considered, that is, the tolerance value of ±15-25mm should be met. Therefore, the hanging member 4 includes the hanging block 41, which can at least meet the height adjustment of ±15mm. In addition to the normal reliable and effective hanging depth, the hanging groove 42 needs to have a height adjustment groove depth that can meet ±15mm.

[0046] In the prior art, the platform brackets, pendants and hanging hooks (43) made of aluminum alloy are limited by the extrusion of profiles and are all thick solid bodies. Not only is the aluminum material poor in bearing capacity, but it is also difficult to fine-process. In particular, 2 / 3 of the thick solid profile is milled off to form the hanging hook 43, etc., and the cost is high, which wastes resources and energy and increases transportation resources.

[0047] Compared with the prior art, in this embodiment, due to the setting of the suspension clearance space cavity a, the insertion length of the suspension hook 43 is not limited. The setting of the long suspension hook 43 not only enhances the stability of the suspension combination between the suspension member 4 and the suspension rod 31, but more importantly, the suspension member 4 can be inserted along the hanging direction. Figure 1 It can be adjusted in the middle Z direction and will not fall off the suspension rod 31. In contrast, the prior art often uses extruded aluminum profiles as platform codes. Due to the limitations of the extrusion process and the strength requirements, the suspension clearance space cavity a cannot be set on the aluminum platform code, resulting in the hanging depth of the suspension member 4 being affected. The suspension member can only be adjusted in the hanging direction at a small distance, which will cause the suspension hook 43 to fall off the suspension rod 31 when an earthquake occurs. In addition, the platform code hanging point is a straight-through type, and there is a risk of slipping under the acceleration impact of the transmitted seismic wave when an earthquake occurs. The comparison test of the full-scale earthquake verified that the prior art has safety risks, and the present invention solves the risk problem.

[0048] Earthquake test model:

[0049] 6m*6m platform for a seismic experiment

[0050] The height of the structural support is 4.5m*4.5m*6m (simulating the height of two floors)

[0051] Input waveforms: El Centro wave from the United States, artificial wave from China, and Wenchuan wave. The ground acceleration of each waveform is input in sequence as 0.2g, 0.4g, 0.6g, and 1.0g

[0052]

[0053] Further, if Figure 3The connecting part 2 is in the form of a plate, and side panels 32 are provided on both sides of one end of the connecting part 2. The two ends of the hanging rod 31 are fixedly connected respectively, and the connecting part 2 and the hanging rod 31 do not overlap in the hanging direction, forming a hanging clearance space cavity a on the side panel 32. The connecting part 2 is retracted and made room in the direction away from the hanging rod 31, which brings more space, and the hanging hook 43 on the hanging part 4 can be hung without restriction, which can maximize the length of the hanging hook 43. The side panel 32 further equalizes the unbalanced reaction force caused by the uneven concrete connection surface of the connecting part 2 and the platform code as a whole, reduces the risk of self-explosion of the curtain wall glass and the risk of cracking of the hanging wall, and can withstand the earthquake shock wave without slipping when an earthquake occurs. The supporting structure can effectively resist the lateral tension and torque generated by the deadweight, wind load, etc. of the curtain wall unit or hanging wall unit during use, ensure the long-term stable operation of the curtain wall and hanging wall, and reduce maintenance costs.

[0054] Preferably, if Figure 3 As shown, the side plate 32 in this embodiment extends to the side of the connection part 2 away from the non-connection surface, and the suspension rod 31 is set at a position lower than the connection part 2. In some special building structure corners, low spaces and other scenes, the lower space can be fully utilized to achieve stable suspension and facilitate construction operations.

[0055] In addition, according to the relevant building load specifications, the negative wind pressure of curtain wall and hanging board wall enclosure structure is greater than the positive wind pressure, especially the corners, roof perimeter, eaves, awnings, protruding balconies, etc. The negative wind pressure is greater. The hook seat for hook connection of the existing platform code is vertically upward, and the bending moment (Mv,cw) generated by the gravity load Va is clockwise. At the same time, the bending moment (Mv,cw) generated by the horizontal tension (N) of the negative wind pressure on the hook seat N ,cw) is also clockwise, that is, the bending moment (W) = Mv,cw + M N ,cw, so the bending moment (W) value is larger.

[0056] In this embodiment, by optimizing the side plates 32 and the reinforcing ribs 33 of the platform, carbon steel plates are preferably selected to reduce the bending moment (Mv,cw) generated by the gravity load Va and the bending moment (Mv,cw) generated by the horizontal tension (N) of the negative wind pressure. N ,cw) is enhanced and inexpensive.

[0057] Furthermore, in order to save materials more reasonably and utilize the counterclockwise reverse force brought by the bending moment (Mv, ccw) generated by the horizontal tension (N) of the negative wind pressure, the present invention makes the height of the suspension rod 31 close to or lower than the plate surface height of the embedded part through the sinking section of the side plate 32 of the platform code and the reinforcing rib, and preferentially selects the plate surface height of the suspension rod 31 to be lower than the plate surface height of the embedded part. The optimal height value of the suspension rod 31 lower than the plate surface of the embedded part depends on the bending moment (Mv, cw) generated by the gravity load Va as the priority consideration value. The steel plate is preferentially optimized through the blanking die, and the suspension rod 31 and the steel plate at the part of the suspension space cavity a are formed into a sinking section by the bending of the side plate 32 of the platform code, and the cost is reduced and the structural performance is improved, so that the height of the suspension rod 31 is reduced. When the counterclockwise reverse force brought by the bending moment (Mv, ccw) generated by the horizontal tension (N) of the negative wind pressure can offset the clockwise positive force equivalent to the bending moment (Mv, cw) generated by the gravity load Va.

[0058] The present invention takes the bearing value data of a certain engineering case in Shenzhen, China:

[0059] The reaction force transmitted from the platform code to the embedded parts is: horizontal shear force (N) = 51.5kN;

[0060] Vertical pressure (self-weight Va) = 7.02 kN;

[0061] Bending moment (M): prior art = 2937620 N.mm; present invention = 1233880 N.mm;

[0062] Tensile strength design value of the platform: 200N / mm for existing aluminum profiles according to 6061-T6 2 , the present invention takes 500Mpa according to Q355 steel;

[0063] Lateral (s horizontal) = 1.6 kN;

[0064] Side bending moment (Ms) = 0.7 kN.m

[0065] Concrete strength Fcn.k=30Mpa

[0066] Embedded surface horizontal eccentricity L = 56mm

[0067] Maximum adjustment ΔL=±25mm

[0068] In order to further obtain the counterclockwise reverse force of the present invention, the data provided by a certain engineering case in Shenzhen, China, is taken for verification and calculation, and it is found that the height of the suspension rod 31 is lower than the plate surface height of the embedded part by ≈11mm, which is the best, that is, the bending moment (M) = 51500×11-7020×(56+25) = -2120N.mm. It is found that when the plate surface of the embedded part is flush with the normal beam surface, the height of the suspension rod 31 is lower than the plate surface height of the embedded part by 35mm, which is the best match between the unit plate beam and the indoor floor decoration with ceramic tiles, that is, the bending moment (M) = 51500×35-7020×

[0069] (56+25)=1233880N.mm, the bending moment value of the prior art is 7020×(56+25)+51500×46=2937620N.mm, so the bending moment value of the present invention is 2.38 times smaller than the bending moment value of the prior art.

[0070] The present invention takes the bearing value data of a certain engineering case in Shenzhen, China, and compares the prior art with the present invention and performs finite element analysis. The analysis results are as follows:

[0071] like Figure 7 As shown, finite element analysis shows that the bearing capacity of the existing aluminum alloy flat platform code is poor. When the horizontal eccentricity of the embedded surface is L=56mm, a large stress is concentrated on the outer cantilever section, which is displayed in red, and deformation occurs.

[0072] like Figure 8 As shown, through finite element analysis of the prior art aluminum alloy flat platform code, when it is magnified 20 times under the action of negative wind pressure, stress deformation occurs in the hanging part of the platform code and the color spectrum shows that the stress is relatively large and is red, and the edge concrete protective layer appears to be subjected to the negative pressure load stress and is displayed in red.

[0073] like Figure 8 As shown, after finite element analysis, the steel plate platform code of the present invention has strong bearing capacity and no deformation; the suspended suspension rod 31 has no deformation, and the finite element chromatogram shows normal stress; and the chromatogram of concrete and embedded parts shows normal stress. It can be seen that the present invention not only solves the problem of coordination between the upper part of the unit plate and the indoor floor decoration by sinking the suspension rod 31, but also offsets the bending moment (Mv, cw) generated by the gravity load Va by counterclockwise offset, thereby saving steel and improving safety. It can be seen from the finite element analysis that when further optimized, the reinforcing rib 33 is preferentially shortened at the dark blue part of the chromatogram, and the plate thickness is thickened, and the bearing effect is better.

[0074] In addition, from the bending moment (M) in the modeling data, it can be seen that the bending moment value changes greatly after adding the maximum adjustment amount ΔL of 25mm. When the external hanging distance of the concrete edge (the horizontal eccentricity of the embedded surface) is considered to be -25mm of the maximum adjustment amount ΔL, L=56mm, and the larger the external cantilever, the worse the stress on the platform. The aluminum alloys in the prior art are worse in terms of bending moment resistance and elongation, especially the 6061 and 6063 aluminum alloy profiles used in curtain walls, which have an elongation of up to 12-25%. In addition, the aluminum alloys used to resist bending moments also have the risk of cracking due to the reduced elongation of the profiles. Of course, steel plates also have a high elongation problem. These are the main reasons for the spontaneous explosion of glass. Figure 6 As shown, the biggest advantage of aluminum alloy is that it can be combined with two refined sliders to form a hanger and a hang plate, so that the hang plate can be lowered to the matching height of the unit plate beam and the ground decoration through 4 sets of adjustment nails. This is also the reason why it has been used despite the high processing costs of milling, tapping, drilling, etc., the thick and heavy aluminum material is expensive and there are more risks. The main reason is that there is no other solution, so it has been used.

[0075] Those skilled in the art may also set the center height of the hanging rod 31 to be flush with the platform code connection part 2, or higher than the connection part, such as Figure 4 As shown, the side plate 32 extends to a side away from the connecting surface of the connecting portion 2, and the suspension rod 31 is arranged at a position higher than the connecting portion 2. For large and heavy curtain wall units or hanging wall units, the higher position of the suspension rod 31 can be used to provide a larger tension arm to enhance the suspension stability.

[0076] Preferably, the connecting portion 2 is provided with a connecting long hole 23, and at least one pair of the connecting long holes 23 is arranged in an eight-shaped shape. During installation, the adjustment margin of the long hole can be used to perform two-dimensional fine adjustment on the platform code 1, accurately compensating for the construction error of the main structure of the building, without the need for additional complex correction procedures, thereby reducing construction costs.

[0077] Furthermore, the connecting portion 2 is also provided with a reinforcing rib 33, which is connected to the suspension rod 31. The mechanical properties of the suspension rod 31 are strengthened, and the ability of the platform bracket 1 to resist external damage is greatly improved without significantly increasing the weight of the material. The platform bracket 1 is not easily deformed or broken under the action of complex external forces such as the deadweight of the curtain wall unit, wind load, and earthquake force for a long time, thereby extending the service life of the connecting components and reducing the frequency of building maintenance.

[0078] like Figure 2As shown, the reinforcing rib 33 is limited by the high sealing requirements between the two columns of the two unit curtain wall panels, and the column width of the unit block is relatively small. The existing aluminum alloy suspension parts are wide adjustment components composed of two extrusion parts fixedly connected, and it is impossible to set reinforcing ribs in the middle. The aluminum alloy flat platform code cannot set up a suspension clearance space cavity a from the principle of bearing. The shortcomings of the existing technology can be clearly seen through finite element comparative analysis. It is even more impossible to open a long groove suspension clearance space cavity for the longer suspension hook of the hanger on the flat plate with poor bearing capacity.

[0079] However, for a platform code, two unit plates need to be hung on the hanging plates at the same time, and because there is a certain deviation in the position of the embedded parts, the length of the hanging rod 31 is usually 240mm-400mm, and the longer the hanging rod 31, the greater its winding, and the hanging rod should not be too thick. Of course, the cross-section of the hanging rod 31 can be rectangular and have wings at the bottom, but from an economic point of view, the price of precision-drawn steel is 1.6 times to 2.0 times that of round steel, and the outward horizontal shear force is greater in terms of force, and from the perspective of the hanging hook (43), horizontal widening is not suitable both economically and technically. Therefore, the hanging rod 31 of the present invention preferably uses round steel and middle ribs, and a hanging space cavity needs to be reserved at the hanging hook (43) to ensure that the hanging hook (43) can slide left and right and adjust up and down through the hanging rod 31, that is, Figure 2 In order to better reduce the width of the platform code and to leave enough space for left and right adjustment after adding the middle reinforcing rib, the reinforcing rib is preferably offset from the center axis.

[0080] In order to achieve the left-right adjustment difference along the axial direction of the suspension rod 31, that is, the L and R directions and the hot and cold sliding functions are not affected, the positioning structure of the suspension member 4 is designed to be installed with an adjustable limit plate 46 and an adjusting bolt 45 on the horizontal plane, so as to adjust the overall horizontality of the unit curtain wall or the hanging board wall. In particular, through the invention of the anti-jump hook 49, the upper control position is effectively reduced, and space for the vertical reinforcing rib 33 is freed up for the present invention. Figure 2 In the embodiment, vertical reinforcing ribs 33 are preferably used to deviate from the center line to obtain more evenly divided left and right adjustable positions. In this embodiment, vertical steel plates with a thickness of 6-10 mm are preferably used as reinforcing ribs, and the maximum thickness should not be greater than 15 mm.

[0081] Preferably, if Figure 1 As shown, the hanging rod 31 is plugged with a hanging member 4, and the hanging member 4 includes a hanging block 41. Figure 5As shown, the hanging block 41 is provided with a hanging groove 42 adapted to the hanging rod 31 for adjusting the height difference depth of the curtain wall and the hanging panel wall. The structure of the hanging groove 42 and the hanging hook 43 is adopted to facilitate the rapid installation and removal of the hanging member 4, simplify the construction process, and improve the efficiency of on-site operation.

[0082] Preferably, the hanging member 4 is also provided with an anti-jump hook 49. After the hanging member 4 is hung on the hanging rod 31, the hook portion of the anti-jump hook 49 is located below the hanging rod 31. This further prevents the hanging member 4 from being separated from the hanging rod 31 when the curtain wall or the hanging panel wall is subjected to external forces such as earthquake waves and wind loads. Those skilled in the art may use a stamping part as the anti-jump hook 49, or a spring hook as the anti-jump hook 49. When maintenance and disassembly are required, the anti-jump hook (49) can be simply pulled out.

[0083] Furthermore, the hanging block 41 is provided with a hanging hook 43 extending in the direction of the hanging rod 31, and a hanging groove 42 is formed between the hanging hook 43 and the hanging block 41, so that the hanging member 4 can move in the hanging direction. This facilitates preliminary positioning and adjustment of the curtain wall unit and the hanging panel wall unit during installation, making it easier to align the curtain wall unit and the hanging panel wall unit with the surrounding structure, and reducing repeated adjustment operations during installation.

[0084] Furthermore, the hanging block 41 is provided with an adjusting nut 44, which is located above the hanging rod 31 when the hanging block 41 is inserted into the hanging rod 31, and the adjusting bolt 45 is screwed on the adjusting nut 44, which presses against the hanging rod 31; the height of the hanging member 4 is precisely controlled, and the fine requirements of the vertical position of the curtain wall unit and the hanging board wall unit for different floor heights or special architectural designs can be met. In particular, in this embodiment, after the hanging member 4 is hung on the hanging rod 31, the adjusting nut 44 and the adjusting bolt 45 face upward, which is convenient for adjusting the height of the hanging member 4 by using an electric tool. The height of the hanging member 4 is precisely controlled, and the fine requirements of the vertical position of the curtain wall unit and the hanging board wall unit for different floor heights or special architectural designs can be met.

[0085] The hanging block 41 is provided with a limit plate 46, and the limit plate 46 is provided with a limit hole 47 and a limit screw 48. The hanging blocks 41 are arranged in pairs and symmetrically, which can effectively constrain the hanging member 4 in the horizontal direction to prevent the curtain wall unit and the hanging panel wall unit from being horizontally displaced due to external forces. In this embodiment, in a pair of hanging blocks 41, the limit hole 47 on at least one of them is a long hole. While limiting the displacement, a certain adjustment margin is retained, which is convenient for fine horizontal adjustment of the curtain wall unit and the hanging panel wall unit in the initial stage of installation, taking into account both installation accuracy and stability.

[0086] Enhance the horizontal stability of curtain wall units and cladding wall units, effectively resist horizontal external forces such as wind loads and earthquake forces, avoid collision and damage between curtain wall units and cladding wall units, and ensure the safety of buildings and personnel. The fine level adjustment function during the installation process ensures that the curtain wall units and cladding wall units are closely and neatly connected with the surrounding structures, improving the overall aesthetics of the building and reducing subsequent maintenance problems caused by improper installation.

[0087] Furthermore, the platform code 1 is connected to the concrete floor beam through the anchor plate connector 5 pre-buried in the concrete floor beam to form a stable embedded connection structure, which has higher connection reliability than the traditional external connection and reduces the potential safety hazards caused by loose connection. On the other hand, it reduces the problem of stress imbalance caused by the uneven concrete installation surface.

[0088] Preferably, the platform code 1 and the suspension member 4 are made of steel. The high strength, good toughness and machinability of steel are utilized to meet the use requirements in complex mechanical environments, while facilitating large-scale industrial production and reducing manufacturing costs. On the other hand, the platform code 1 and the suspension member 4 are made of the same material to avoid electrochemical corrosion due to different material potentials. Compared with the prior art, the platform code 1 is usually made of extruded aluminum products, which are prone to galvanic corrosion with embedded parts. When the platform code 1 is a steel plate, although the potential is the same as the embedded part, galvanic corrosion will occur between the steel plate platform code 1 and the aluminum alloy suspension member, and an insulating flexible protective cover is arranged between them. Due to the thermal expansion and contraction of the suspension member sliding on the platform code and the gravity of the plate, the wear protective cover causes the platform code 1 to be in direct contact with the suspension member and electrochemical corrosion occurs. Under the action of tension and bending moment, there will also be uneven flatness differences at the four points connected in each unit, which makes the glass have a higher probability of self-explosion when the temperature changes. Similarly, the anchor foot connector that rests on the platform bracket 1 is made of steel.

[0089] When the unit plate is added with vertical decorative strips, it usually needs to withstand 20-40 kN lateral force under the lateral wind pressure, as well as side sliding under earthquake shock waves, etc., but the space is too narrow and the installation conditions are limited. Preferably, the hanging member 4 of this embodiment is provided with a connecting groove 6, and a top rod bolt 61 parallel to the hanging rod 31 is connected in the connecting groove 6. One end of the top rod bolt 61 is pressed against the reinforcing rib, and the other end is screwed with a top nut 62 and pressed against the side plate 32. A pair of clamping nuts 63 are also provided on the top rod bolt 61, and the clamping nuts 63 are arranged on both sides of the hanging block 41. The hanging plate is fixed by screwing the top nut 62, and one side is tightened by the clamping nut 63.

[0090] like Figure 6As shown, in the prior art, the hook and the hanging plate are connected with the female thread on the hanging plate by adjusting the male thread of the nail b and the height is adjusted by the thread. The adjusting nail is usually made of stainless steel, and there is a large potential difference with the thread tapped on the aluminum hanging plate. Therefore, from the principle of potential, the anode is the one with a small potential, and the anode part will be galvanically corroded. When the standard potential value of stainless steel is -120 to -240mv, and the standard potential value of aluminum alloy is -1670mv, the aluminum alloy thread is the anode. Since the potential difference between the two is very large, the galvanic corrosion rate is fast. Damaging the thread will cause the entire curtain wall or hanging plate wall to fall off, especially in coastal and rainy areas, where the galvanic corrosion hazard is more hidden. Although in theory, the potential of the cathode stainless steel or carbon steel can be reduced by an insulating plate, or the potential value can be reduced by surface purification, surface zinc-aluminum alloy and other measures to slow down the electrochemical corrosion, but the difference with the aluminum alloy -1670mv anode is too large, so the electrochemical corrosion is slowed down less.

[0091] The anchor plate connector used for the above-mentioned unit-type embedded plate connection assembly includes an anchor plate 51, and the anchor plate 51 is connected to an anchor foot 52 embedded in the edge of the floor slab concrete. This embedded structure is integrated with the floor slab during the concrete pouring process, providing a strong anchoring force to ensure the reliable connection between the connection assembly and the main structure of the building. The one-piece embedded structure enhances the pull-out resistance of the anchor plate connector, enabling it to withstand the larger vertical loads of the curtain wall unit and the hanging panel wall unit, ensuring the stability of the curtain wall and the hanging panel wall in the vertical direction, and is particularly suitable for high-rise and super-high-rise building curtain wall and hanging panel wall projects. Those skilled in the art should know that the anchor foot can be replaced with anchor bars, anchor bolts, or any combination of anchor feet.

[0092] The anchor plate 51 is provided with a support portion 53 at the edge of the floor concrete and the hanging side of the hanging member 4. It provides additional vertical support for the platform code 1, optimizes the force distribution of the curtain wall unit and the hanging wall unit, and further avoids the defect of uneven stress on the hanging rod 31 due to uneven ground. The setting of the support portion 53 makes the force of the curtain wall unit and the hanging wall unit more balanced, reduces fatigue damage of the connecting components caused by excessive local force, extends the fatigue life of the connecting components, and improves the reliability of the curtain wall and hanging wall system. The stable support platform 54 works in coordination with the hanging rod 31 to significantly improve the vertical bearing capacity of the curtain wall unit and the hanging wall unit, ensure the safety of the curtain wall and the hanging wall during long-term use, and adapt to the requirements of various complex building structures for the bearing of the curtain wall and the hanging wall.

[0093] Preferably, the support portion 53 is formed by tilting from the edge of the anchor plate 51 toward the platform code 1. Preferably, the top of the support platform 54 is flush with the bolt connection platform of the anchor plate 51, and the support platform 54 forms a plane with the anchor plate 51. The structure is cleverly designed. Without applying force to the edge of the concrete beam, it provides a stable support point for the platform code 1, protects the edge of the concrete beam, and transmits the bending moment and shear pressure from the platform code 1 for balanced bearing. Therefore, it can be applied to concrete beams with reduced cross-sections, and through the support portion 53, the supporting rod fulcrum can effectively reduce the size of the platform code and the thickness of the steel plate. And it is flush with the bolt connection platform of the anchor plate 51, which is convenient for installation and docking. A support platform 54 is formed at the top to be carried above the floor slab concrete, so as to avoid direct contact between the platform code and the uneven base surface of the poured floor slab or beam surface, protect the floor slab and beam structure, and facilitate later inspection and maintenance. Not only saves engineering costs, but also increases the rigidity of the platform code 1 and improves the connection stability.

[0094] Those skilled in the art may also design the support platform 54 formed by the raised edge to be a support boss flush with the connecting protrusion of the anchor plate 51 .

[0095] The research and development of weld-free assembled embedded parts that can meet the needs of ultra-low energy consumption (passive) building projects will be conducive to the global promotion of full-life green building assembly and ultra-low energy consumption in the construction industry, while also helping China's construction and curtain wall industries to go abroad and serve the world.

[0096] The present invention provides a low-conductivity insulating plate between the anchor plate 51 and the concrete. The thickness of the low-conductivity insulating plate can be selected from 2 to 10 mm according to the design energy saving. From the perspective of material compression and load-bearing ratio, the low-conductivity insulating plate preferably has a thickness of 3 to 6 mm. From the perspective of energy saving ratio, the low-conductivity insulating plate preferably has a thickness of 6 to 10 mm. From the perspective of energy saving ratio and material compression and load-bearing ratio, the optimal thickness is 3 to 8 mm. Preferably, non-thermal conductive conductive fiber filaments or low-thermal conductive non-conductive fiber filaments are added to the low-conductivity insulating plate. The non-thermal conductive conductive fiber filaments can be plant fibers, rock fibers, and chemical fibers, and basalt fibers are preferably selected. When selecting low-thermal conductive non-conductive fiber filaments, carbon fibers are preferably selected. In this embodiment, a high-strength, low-conductivity insulating plate is selected.

[0097] Furthermore, the anchor plate 51 is provided with a stretching protrusion space for installing the blind installation head of the connecting bolt. Fig.10 As shown, the edge of the anchor plate 51 and the high-strength low-conductivity insulating plate are preferably bonded. The stretching protrusion space of the blind installation head of the mounting connection bolt, where the edge of the anchor plate 51 is bonded to the high-strength low-conductivity insulating plate, is filled with a thermal insulation foaming agent. Preferably, the thermal insulation foaming agent is a chemical foaming agent or a physical foaming agent that can be thermally insulated.

[0098] Furthermore, the anchor plate 51 is provided with anchor bars, anchor feet, and anchor bolts. A low-conductivity insulating layer is provided between the surface of the anchor bars, anchor feet, and anchor bolts and the concrete. The low-conductivity insulating layer can be a coating on the surface of the anchor bars, anchor feet, and anchor bolts, or can be injected with glue in prefabricated holes.

[0099] Furthermore, the hanging block 41 is provided with a low-conductivity insulating layer between the hanging block 41 and the connected column, and the low-conductivity insulating layer can be a plate or a coating.

[0100] The embedded parts of the present invention propose a new concept of using low conductivity and insulation to cut off heat and cold. Through research and a large number of experiments in multiple cross-fields of materials, mechanics, and chemical engineering, it is found that the aluminum alloy connected at both ends of the embedded parts has a thermal conductivity of 2.5w / m2.K and the concrete has a thermal conductivity of 2.94W / m2.K, which are the largest thermal conductors. It is also found that the main heat and cold conduction from the outside is introduced by the connecting bolts between the external aluminum profile and the indoor aluminum profile. Since an insulation layer may be provided between the external curtain wall or the hanging board wall and the main body of the building, the internal aluminum profile can only be conducted to the metal embedded parts through the metal adapter or the metal hanging block (41) connection surface and the metal bolts, and then the heat and cold are introduced from the metal embedded parts into the concrete to affect the indoor temperature. For this reason, the present invention adopts the large-area contact between the aluminum material and the steel plate and isolates it with low thermal conductivity insulation materials, so that the bolt and the pipe wall hole on the column with a larger diameter than the bolt form a point contact introduction source. The concrete and the embedded anchor bars and anchor feet are treated with insulating coatings, and the anchor bolt installation holes are injected with resin glue.

[0101] The compression test of low thermal conductivity insulation high strength board with added fiber of 3mm, 6mm, 8mm and 10mm and the thermal conductivity test of embedded parts with added low thermal conductivity insulation high strength board were carried out respectively. The results showed that the fatigue compression performance was the best in the thickness of 3mm-6mm, the thermal conductivity test thickness was the best in the thickness of 6mm-10mm board, and the comprehensive fatigue compression + thermal conductivity test was 3mm-8mm. The thermal conductivity test was provided with a heating area (outdoor) and an indoor area. In the indoor area, temperature sensors were set at 100mm and 150mm of the anchor foot and anchor bolt in the concrete. The test results showed that when the heating area was heated to 80℃ for 1h / 3h / 6h, no temperature change was observed in the set temperature sensor, indicating that the present invention has a significant effect of blocking heat and cold through insulation, and is suitable for ultra-low energy consumption building applications.

[0102] In this embodiment, the anti-jump hook 49 is made of elastic wire, and those skilled in the art may choose carbon steel or stainless steel. Fig. 9As shown, one end of the anti-jump hook 49 is bent into a U-shape to form a drum-shaped head. The largest part of the drum-shaped head is larger than the inner diameter of the first connecting hole B, and is compressed by external force and inserted into the first connecting hole B to open and clamp in the first connecting hole B. The connecting head section at one end away from the drum-shaped head opens outward to position the single-wire head for insertion into the second connecting hole C. The middle part of the anti-jump hook 49 is provided with an arc buckle section 491 which can prevent the suspension hook 43 from jumping out of the suspension rod 31.

[0103] During installation, the connecting head section is first pre-inserted into the second connecting hole C, and then the drum-shaped head is inserted into the second connecting hole B by pressure. The outermost distance from the second connecting hole C to the first connecting hole B is less than.
